US 11548565 B2 Side Vehicle Body Structure Of Vehicle
Abstract
A side vehicle body structure ensures rigidity and shock absorption performance of the body, avoids widening of the body, and smooths the flow of exhaust gas. Embodiments include an engine, an exhaust apparatus, and a rear pillar extending upward from a rear-side portion of a side sill extending in the vehicle front-rear direction. The exhaust apparatus is disposed along the vehicle front-rear direction on the vehicle-width-direction outer side relative to the side sill. An exhaust system member is located at a going-around portion, with respect to the rear pillar, from the front side to the rear side and from the outer side to the inner side in the vehicle width direction. The rear pillar has a cross section orthogonal to the vehicle up-down direction having a shape in which a portion between front and rear ends is located on the vehicle-width-direction outer side relative to these front and rear ends.

US 11529996 B2 Front Vehicle-body Structure Of Vehicle
Abstract
A front vehicle-body structure of a vehicle is provided that allows for lower deceleration (so-called G) for occupants in the event of an oblique collision, which involves the largest load input, while restraining a load in a shear direction from being input to connecting portions of frames. A front vehicle-body structure of a vehicle includes a suspension housing formed with a suspension damper supporting portion, an upper arm supporting portion, and a lower arm supporting portion. A plurality of frames connecting the suspension housing and a vehicle cabin structural member are provided, and at least one frame of the plurality of frames is configured to be facilitated to break in a Z-shape in vehicle plan view in the event of an oblique collision.

他にもスペースフレーム構造を車両に関する特許を出願しているかもしれないです。ここに取り上げたものは、2022年12月から2023年1月と最近出願されています。国内では2021年に出願しているものです。
発明と量産は必ずしも結びつきはしませんが、アメリカでも特許を出願するということは…考えすぎでしょうね。
